--- Generates the cLuaState::Call() function templates that are included from LuaState.h
-
---[[
-The cLuaState::Call() family of functions provides a template-based system for calling any Lua function
-either by name or by reference with almost any number of parameters and return values. This is done by
-providing a number of overloads of the same name with variable number of template-type parameters. To
-separate the arguments from the return values, a special type of cLuaState::cRet is used.
